described above should nevertheless be necessary, this equipment

and the other equipment should be checked for proper operation.


This device emits UV radiation through the transparent comb

attachment, which can cause eye or skin irritation. Avoid the UV

radiation of eyes and healthy skin. The UV radiation is not visible for

the human eye and can lead to corneal inflammation (photokeratitis)

and eye inflammation (photoconjunctivitis) within a short time.

It is imperative that during a therapy session, you wear the UV

protective goggles included in the scope of delivery. Simply closing

your eyes without protective goggles during a therapy session does

not offer sufficient eye protection. Also, avoid looking into the UV

lamp with unprotected eyes; immediately switch off the therapy

device after treatment and also during short-term interruptions in the

treatment session.

Never operate the device without comb attachment.

UV-radiation can cause the skin to get sun burnt within a short time.

It is imperative that you pay attention to the therapy

recommendations specified in the user manual.

To avoid erythema (sun burn), healthy skin (e.g. ears) must be

protected with a high protection factor sun cream, which is to be

applied to those areas in due time before the treatment session (see

page 8)

The intensive use of the therapy device over years can promote the

development of skin cancer. Avoid excessive sun exposure during

the treatment cycle; also, adjust your leisure behaviour during this

time. You should not visit tanning studios while using the device in a

treatment cycle.

At the start of the therapy, approx. 3 - 5 treatments per week are to be conducted.

Exposure time depends on the patient’s individual sensibility and skin type.

Special care has to be taken never to reach the erythema threshold (development

of sun burn). We refer to the specific instructions in this user manual. Due to the

intermittent appearance of clinical symptoms, an according maintenance therapy

in a domestic setting is indicated.

The treatment is conducted based on a doctor’s recommendation and in

accordance with the treatment guidelines laid down in the user manual. Any other

use going beyond or deviating from the defined scope of usage is considered

„improper use” and may lead to health impairment and injury.

6 Basic Information on UV Phototherapy

UV phototherapy is an

established procedure,

recognized for decades for the

treatment of various skin

diseases, particularly

psoriasis, neurodermatitis and

vitiligo. UV radiation affects

the upper skin cells and, after

repeated application, positively

influences the immune system

and the skin‘s regeneration behavior. Depending on the clinical picture, selected

UV-spectral ranges (UV-B and UV-A) are applied, which in low strength are also

present in natural sunlight.


7 Indications

According to version (UV-B narrowband, UV-A1) and recommendation by a

medical professional, the Saalux® UV comb is used for the following indications:

Psoriasis

Vitiligo

Neurodermatitis

8 Contraindications

The UV therapy must not applied in case of:

Tumorous skin changes

Abnormal sensitivity of the skin to light, e.g. Xeroderma

Pigmentosum

Porphyria disorders

Florid Tuberculosis or other active processes

Hyperthyroidism

Lupus Erythematosus

Accompanying medicinal treatment with potential skin

damage

Increased sensitivity to light

Following side effects may occur:

Erythema (sunburn)

Dry skin

9 Initial Operating Instructions

The device may only be used with a power supply that matches the supply

voltage specified on the rating plate. To ensure safe operation of the unit, all its

cables, plugs, control elements, and housing components must be in faultless

condition. Prior to each use, check the device for possible damage; a defective

unit may not be operated. Pay attention to the references on the unit and in the

user manual. Please switch the unit off after you finished a treatment session.


10 Therapy Recommendation

Removing dandruff:

Plaques and scales absorb

the UV radiation and prevent

the UV radiation from

penetrating into the diseased

skin layers. In case of

extensive infestations,

thoroughly remove plaques

and scales before starting

the UV therapy (e.g. with the

Saalux dandruff solution, see back page).

UV protection

Prior to starting the treatment, all healthy skin areas (the ears, amongst others)

should be covered or creamed with an according light protection screen in due

time (please consider application time!).

Prior to or during a therapy session, the skin must be free of topical applications

like, e.g. ointments; do not use sun protection on the skin that is to be treated.

Certain pharmaceuticals increase the skin‘s UV-sensitivity, a fact you might want

to discuss with your physician! Since scales on the scalp can impact treatment

success, a thorough cleaning prior to the treatment session is imperative.

Moreover, moist skin has a better UV-absorption which means that the treatment

of moist skin (possibly after washing) can accelerate the therapeutic success.

Moisty skin

Moisty skin is more receptive for UV radiation. Therefore the application on

moisty skin (e.g. after washing the scalp) may accelerate the therapy success.

Operation of Timer

At the onset of the treatment session, please make sure that the count-down

timer is functioning properly (e.g. battery o.k.?)

Prior to starting a treatment session, plug the device into a suitable outlet, put on

the protective goggles and keep the device switched on for approx. 5 min in order

to achieve a stable UV-output.


Please set the provided count-down timer by

pressing the according buttons „MIN“ for minutes

and „SEC“ for seconds to the desired treatment

time. Pressing the „Stop/Start“-button starts or

interrupts the countdown for treatment time. By

simultaneously pressing both „MIN“ and „SEC“

push buttons, the count-down timer resets to

„00:00“.


Finding the right dose and treatment duration:

It is common nowadays to use the classification made by the American

dermatologist Thomas Fitzpatrick in 1975 to define various skin types. Dark skin

types (type 5 and 6) are very rare at our latitude and thus are not taken into

account here.

The following applies:

Persons of skin type 1: (pale white skin; blond or red hair - always burns,

never tans) are not suitable for UV-therapy!

Skin type 2: fair; blond hair - usually burns, tans minimally (fair European type).

Skin type 3: fair, light-brown or brown hair, tans uniformly after repeated sun

exposure (dark European type T).

Skin type 4: brown or black hair - rarely burns, always tans well (Mediterranean

type)

The following dosage is recommended for patients of skin type 2, 3, and 4.

Please note that these doses refer to the treatment of the entire scalp and

never just to one spot which would result in an overdosage in the form of an

erythema (sun burn)! Special attention should be paid to the inner surfaces of the

outer ears. They should not be treated for an extended period since they are

extremely sensitive to UV light (light protection screen see above).

The treatment times indicated are mere guide values; please consult with your

dermatologist to determine your individual numbers. Upon reaching the highest

dosage indicated for the according skin type, it is not sensible to increase further

the dosage arrived at is to be maintained. Keep in mind, however, that excessive

doses can lead to an acute aggravation of your skin condition (the so-called

Köbner phenomenon) and too low doses result in an unnecessarily increased

„lifetime dose“ without the desired therapeutic success.


Dosage recommendations for Psoriasis with UV-B narrowband

Conducting the Therapy

Only use the device in a dry environment. Always use the UV protective goggles

provided and never look into the UV lamp with unprotected eyes! While you

conduct the treatment, there should not be any additional persons close by

(exposure to scatter radiation).

Always protect your eyes with

the UV protective goggles!

According to skin type, start the therapy of the entire scalp with 3 (skin type 2),

3.5 (skin type 3) or 4 (skin type 4) minutes. Please position the count-down timer

where it is easily visible and acoustically perceivable for you; after counting down

to zero, an acoustic signal will sound for approx. 30 seconds. You can turn it off

by pressing any button. After pressing the Start/Stop button, the previously set or

lapsed time will appear in the display again.

The treatment is to take place slowly, distributed uniformly over the head and

against the direction of hair growth with parallel alignment of the radiation source

to the skin. The hair parter or comb attachment facilitates reaching the hairy scalp

skin and ensures the required treatment distance.


Other skin lesions (besides those on the scalp) are treated in an identical way but

always with mounted comb attachment.

The treatment should be conducted three to five times weekly. The duration of

the treatments depends on the severity of the skin disease. Generally, 20 - 25

sessions should be sufficient for the skin conditions to subside. A prolonged

maintenance treatment is not recommended.

Therapy monitoring:

Following every treatment session, monitor the treated skin areas for therapeutic

success as well as for possible side effects:

Should you discern side effects like a sun burn or painful change in the diseased

skin, you have to reduce the dose for the next treatment by 40% and you may

only continue with the treatment after the side effects have abated. If in doubt,

consult your attending physician.

Should you discern side effects like a sun burn or painful change in the healthy

skin, make sure to provide better protection for the next treatment like using

sunscreen with a high protection factor or more carefully cover these areas with

textiles..

Should you not experience any successful therapy outcome at all, gradually

increase the dose as described in the tables. If you have reached the maximum

dose according to your skin type and still do not notice any therapeutic effect, the

service life of the UV lamp may be expired (see chapter 14). If in doubt, consult

your attending physician.

After every individual treatment, document your

therapy outcome and success in the patient diary

provided and discuss your therapy results regularly

with your attending physician.


End of a treatment series:

To maintain the positive treatment outcome, it is recommended to „phase out“ the

therapy after the lesions have disappeared. This can be done by e.g. decreasing

daily treatment for the next 3 weeks to 3 times weekly, for 3 weeks to 2 times

weekly and for 3 weeks to once a week.

11 Cleaning and Disinfection

Prior to cleaning and disinfecting, switch off the device and pull the plug from the

outlet. Let the device cool off before you begin cleaning. You achieve better

cleaning results if you pull the comb attachment from the unit and clean it

separately.

Wipe the comb housing with a

moist cloth. If needed, the comb

attachment can be detached from

the housing and cleaned on the

inside and outside under running

water with a mild soap or dish

detergent. Avoid wiping either

device or comb attachment with a

dry cloth which can scratch the

surface.

Do not use aggressive or solvent-based cleaners. These affect the surfaces of

the device. Avoid any penetration of liquids during cleaning.

When using the device by several patients, the comb attachment must be

cleaned and disinfected before any patient change, in order to prevent infections

between patients. The following disinfectants can be used for this purpose:

• Descosept Spezial (wiping disinfection)

• Microzid sensitive liquid (wiping disinfection)

• Sani Cloth Active (wiping disinfection)

For a sufficient disinfecting effect, the application instructions of the respective

manufacturers must be observed. If other disinfectants are used, only products

suitable for acrylic glass are to be selected.

12 Transport and Storage

Protect the UV comb during transportation from undesirable shocks; the UV lamp

may be damaged (glass breakage). Store the therapy device in dry rooms and do

not expose it to high temperatures.


13 Errors and Troubleshooting

UV lamp does not light - Check the outlet or use another outlet. Verify that

the UV lamp is tightly inserted into the socket.

First switch off the device and unplug the power

cord.

If this did not fix the problem, contact the address specified in the manual.

14 Life cycle and service life

The service life of the UV comb is essentially dependent on the frequency of use.

The average service life of the UV lamp is 500 hours. After this runtime, UV-

radiation decreases. This also becomes evident by a decreasing therapy result. A

defective or poor UV lamp may only be replaced by the manufacturer or

professionals trained and authorized by the manufacturer. The use of a wrong UV

lamp can cause burns. After replacing the UV lamp, the treatment duration has to

be determined again (see chapter 10).

15 Maintenance and Repair

For commercial use the manufacturer recommends to carry out maintenance at

the latest every 2 years, which is generally also recommended for private use.

The commercial user is responsible for complying with all applicable national

regulations and inspections (e.g. occupational safety).

For maintenance or repair ship in the original packaging if possible. Please make

sure that the device is protected against shocks and that packaging is suitable for

the method of shipment selected.

Please don’t forget to clean the device and accessories prior to shipping it!

16 Warranty

The UV comb has been manufactured and tested with the greatest care. Should,

however, a malfunction occur, we grant you a manufacturer warranty for all

defects caused by material deficiency or manufacturing error. The manufacturer

warranty extends over 4 years for final customers/consumers and 2 years for

commercial customers (applicable are the provisions of the manufacturer‘s

general terms and conditions in the version in force at the date of purchase).

Any intervention on the therapy device by buyer or third parties renders the

warranty claim void. Any defects or errors which are or might be caused by


improper handling or disregard for the „intended use“ or the user manual, result in

the immediate loss of warranty claims against the manufacturer.

Categorically excluded from all warranty claims are wear parts or glass breakage

(e.g. the UV lamp). Also excluded from the warranty is the UV-intensity of the UV

lamp.

Should you have any reason for a claim, please get in touch with us. The contact

information is specified in the user manual.
